Abstract: Energy efficiency is an important design consideration in hybrid ad hoc network due to the limited battery life of mobile terminals. The network lifetime will be improved by suitably reducing the requirement of power for connections. The objective of this paper is to develop a novel routing protocol for hybrid ad hoc networks. We proposed the enhanced version of ad hoc on-demand multipath distance vector (AOMDV) routing called power aware link stability routing (PALSR) protocol for energy conservation and establish a desired hybrid connection between MANET and internet. The proposed PALSR protocol uses a new metric to find the route with higher transmission rate, less latency and better stability. It checks bandwidth and delay constraint during route request and uses as well new mobility prediction mechanism to determine the stability of link during a path selection. We evaluate the performance of PALSR using NS-2.34 simulation tool and compare it with AOMDV protocol. The simulation results show that the performance of new routing protocol significantly improves the network performance by discovering the required path with minimal power and delay.
